問題描述

當我們在某個字段上分組行時，如何為 JQGrid 進行全局展開/折疊?

How can we have global Expand/Collapse for JQGrid when we have rows grouped on some field?

展開時，應展開所有組，折疊時應折疊所有組.

On expanding, it should expand all groups and on collapsing all groups should be collapsed.

推薦答案

同樣的方法可以設置jqGrid的groupingView參數的groupCollapse屬性的默認值就像您設置任何其他默認參數一樣:

You can set default value of the groupCollapse property of the groupingView parameter of jqGrid in the same way like you set any other default parameter:

$.extend($.jgrid.defaults, {
    groupingView: {
        groupCollapse: true
    }
});

已更新:在評論中進行了額外解釋后，我可以想象在某些情況下，當 所有 組從組將被展開/折疊.

UPDATED: After additional explanation in the comments I can me imagine that in some cases it can has the behavior when all groups will be expanded/collapsed if any from the groups will be expanded/collapsed.

var $grid = $("#list"), inOnClickGroup = false;

$grid.jqGrid({
    // ... other options
    grouping: true,
    onClickGroup: function (hid) {
        var idPrefix = this.id + "ghead_", id, i, l,
            groups = this.p.groupingView.sortnames[0];

        if (!inOnClickGroup && hid.length > idPrefix.length &&
                hid.substr(0, idPrefix.length) === idPrefix) {
            id = Number(hid.substr(idPrefix.length));
            if (typeof (groups[id]) !== "undefined") {
                inOnClickGroup = true; // set to skip recursion
                for (i = 0, l = groups.length; i < l; i++) {
                    if (i !== id) {
                        $(this).jqGrid('groupingToggle', this.id + 'ghead_' + i);
                    }
                }
                inOnClickGroup = false;
            }
        }
    }
});
